I agree with Olivia, a week is plenty time to book another hotel. Go back to tripadvisor.com and type in Aruba and the top rated hotels will come up for you to read reviews. As Lauri said, I remember the Hyatt being very nice and it's on the main beach.

After you figure out what hotel you wart, you can do a few searches at the hotel booking sites to see who has the cheapest and book it through one of them. You can be done with the process by tonight. I even think that Tripadvisor has a doohickey that will search all the hotel booking sites for you.
